My mental image of you is completely incompatible with paintball.
My neighbor's son works at a gun shop, and he builds custom anythings for people. He brought over an AR that had an adjustable carbon fiber sleeve down the barrel, which could be tightened or loosened depending on temperature and conditions to control the flex of the barrel when it fired. This apparently greatly improves accuracy. It also had a scope that felt like I was looking into another dimension it was so large and easy to see into.
So I shot it at bowling pins at 100yds and didn't miss a single one, which for me is impressive because I naturally shake like Michael J Fox on a cold day. Scary how easy it would be to hit a body at long range with that thing.
A few years ago, I was up on my roof taking down christmas lights, and the concussion from whatever the fuck he shot scared me so badly I almost went tumbling off. Their house is probably 75yds away, and they shoot on the far side of it out into the hillside.
He was sighting in a .50 caliber for a client, and I damned near died.
